众所周知,油气在盆地内的分布是不均匀的。人们在研究含油气盆地的形成及演化时,认识到断裂对油气聚集分布起着控制作用。我国许多含油气盆地内的油气聚集受断裂控制,如胜利油田、华北油田、四川气田。西北区的油气分布,与断裂关系更为密切。如克拉马依油田、塔里木盆地西南拗陷、柴达木盆地西部朵斯断陷、酒西盆地老君庙背斜带、陕甘宁盆地西缘马家滩断褶带,其油气聚集分布,无不受断裂控制。

While searching for petroleum in petroliferous basin formed by compressional stress,much attention must be paid to the faults developed on the margin of a basin;and to the drag folds and faulting blocks which were formed due to faulting.In these areas,petroleum is likely to accumulate,and to form a petroleum field.The formation,evolution of a petroliferous basin and petroleum accumulations are closely related to faulting.For example,the petroliferous structural zones of the petroleum distributing area in Northwest China are mostly controlled by faulting.
